Abstract: A bridge is very important structure nowadays. The bridges have become much more efficient with technological advancements. There are various types of bridges available. The box girders are suitable for a variety of bridges. Box girders are efficient and also economical superstructures. The study presented here shows parametric analysis of an Inverted Triangle Box Girder Bridge. The parametric study is carried out to get the basic idea of section performance under the section depth variation. The longitudinal and lateral (cross-sectional) analyses have been carried out. The longitudinal designing is done using the Simple Beam theory and design ideology is Limit State Design. The section is analyzed and designed for Shear force, Bending moment and Torsional moment. The software used for the analysis in this study are CSi Bridge and Bentley STAAD Pro, while the designing is carried out using Microsoft Excel. The reference codes used are Indian Standards. The section shows satisfactory performance for most of the cases.
